ya.. that or the 3800 are the normal swaps...
or echotech but mine is a pace car.. so I'll keep the duke.. it goes nicely with it.. and 38mpg hyway and 27ish around town.. and that was why I bought it.. 4cyl good mpg and american made and somewhat fun to drive daily..

I have it in a 23 T-Bucket and has plenty of power for a light thing like that only 1,380 lbs, so moves along real smoothly.

Thanks everyone for your input it shows that there is a lot of intrest in the old 151.

Post a few pics Id really Be interested in seeing it!!!

He may only need a simple answer!

That may be a marine iron duke?

Header companies advertize hp gains but not at what rpm ranges.Off idle gains for headers amounts to not much.At least not much for the seat of the pants dyno.To tune a highly mod engine's exhaust is something entirely different.The expectation going in is to operate that engine at a higher rpm anyways where headers effectiveness come into play.

He won't see a huge increase with an otherwise stock engine but he can see a measurable increase if he does a good job. Anytime you work with an NA 4 banger you expect small incremental gains. BTDT

Lets say I'm running a street rod With an exposed engine? I would want a classy looking exhaust with a header ! That may be what the thread starter has in mind.

Wait till he comes back and you can warn him his engine is going to fly apart! And he built the wrong engine! And you can school him in the way he should have done it!!!!! And post pics to show him what kind of exhausts you have built!

true.. but.. the iron duke bottom end isn't strong enough to get the rpm's up high enough to run out of flow..
I understand that different tube lenth/size/ collector lenth/size/type can help...
g.m. got 6hp after a new head and roller cam.. and a balance shaft..
the newer head doesn't fit the older block..
'86 it got roller cam.. '87 disII ign ''88 oilfilter in pan (IIRC) balance shaft came online around now.. or allitle later
